  • any other transmission mode could be used in place of the chains 12, 13 and 14.
  • the transmission chains 12, 13, 14 may for example be replaced in whole or in part by belts.
  • both gearbox gearbox 10 and transmissions 12, 13 and 14 can have a constant reduction ratio, the engine torque being able to be dimensioned so as to dispense with a transmission with discrete ratios.
  • the electric motors used are wheel motors 17, 18 sealed.
  • Wheel motors are electric motors with permanent magnets whose thickness is relatively small compared to the diameter.
  • the wheel motors 17, 18 used may be motors of the "e-wheel” series manufactured by the company PML Flightlink Ltd. More particularly, the engines used are EW3030 engines.
  • This type of engine has many advantages.
  • this type of engine has a high torque at low speed.
  • the motor means do not include reducers.
  • the rotational speed of the wheel motors 17, 18 is adjustable with very high accuracy. Therefore, both wheel motors 17, 18 actuating each wheel set can be synchronized with very high accuracy.
  • the wheel motors 17, 18 have an excellent performance and a power ratio delivered on high weight.
  • wheel motors 17, 18 also allow energy recovery during braking.
  • the wheel motors 17, 18 are brushless motors, which reduces maintenance and improves reliability in a humid environment.
  • the motors are powered by a three-phase DC power supply.
  • the electrical control of the motors is carried out by an electronic control unit 16.
  • this electronic box 16 is arranged to allow the use of all types of batteries whose voltage is between 12 V and 72 V.
  • This housing 16 also has a phase advance switch which maximizes engine efficiency 17,18.
  • FIGS 3 and 4 illustrate the arrangement of the motor means according to the second embodiment of the invention.
  • a plate 19 is fixed to the frame 1 of the vehicle and carries two vertical plates 20, 21 for fixing the wheel motors 17, 18. To reinforce these two vertical plates 20, 21, plates of reinforcements 22, 23 are arranged between the support plate 19 and the fixing plates 20, 21.
  • the wheel motors 17, 18 are fixed on the vertical plates 20, 21 and the output shafts 24, 25 of the motors 17, 18 are oriented towards the wheelsets to be driven.
  • the driving of the wheels 6, 7, 8 is carried out using transmission chains 12, 13, 14 as described above and / or belts.
  • the accumulators 11 are disposed near the center of the vehicle and downwards which improves the stability on land and in particular on water.
  • the batteries represent a significant weight which can advantageously be used as a ballast allowing, when it is well positioned, to stabilize the vehicle.
  • the motors 17, 18 can play alternately or in addition to the batteries, the same role balancing weights.
  • a control lever 15 of the joystick type provides in a known manner two control signals according to its angular position. These control signals are addressed to an electronic control unit 16. In the embodiment detailed in FIG. 1, the control unit 16 synchronizes the geared motors 10 as a function of these control signals.
  • the electronic unit 16 synchronizes the wheel motors 17, 18.
  • the synchronization of the motors can consist in synchronizing the speed of rotation of the motors, for example by a system of rotation counter integral with the wheels or motors, or synchronizing the power supply of the motors.
  • the precision of the motor synchronization makes it possible to precisely maintain a heading or to maintain precisely a curvature. Accurate synchronization of the motors also makes it easy to perform self-gyrations, ie pivoting on the spot.
  • both engines are in maximum recovery to slow down the vehicle as it moves forward. It is also the recoil position. Again, the housing 16 provides the same speed of rotation for both engines.
  • one of the motors rotates in one direction and the other is stopped to allow rotation of the vehicle in one of the advance directions.
  • positions H and I correspond to positions F and G with the motor rotating in the other direction which allows a rotation of the vehicle in the other direction of advance.
  • positions F, G, H and 1 constitute intermediate ranges for dosing the speed and couples to bring into play to have maximum comfort of use.
  • the assembly operates without liquid cooling, so virtually maintenance-free, from one end to the other of the drive train.
